C precompiler macros can be (and are) used to provide generic-like semantics.
Go has no such "blessed" precompiler-macro system.
Templates/macros are an ugly solution, but they are a solution.

So yeah, the toolset may not have anything like the C's preprocessor (the lack of which is a blessing, not a curse, IMO), but that's fine, if you're sure you really need such a thing just spend half a day writing your own in Go that is specific to your project's needs and make that a part of your local build process.
No real tooling either other than whatever you choose to use for the build process. For the projects I've done this for that ends up being a very simple Makefile which does a 'go run' on the code generation engine code prior to a 'go build' of the resulting combined package of generated & hand-written code.

I've never used gen, it looks pretty nice though, at least based on the linked docs and it is probably a good answer to Pxtl's question about publicly available examples.
Tangential, but a decent example of that sort of thing, a generic red-black tree written entirely in the C preprocessor: http://www.canonware.com/download/rb/rb_newer/rb.h
